Application filed September 8, 1915. Serial No. 49,606.

To all whom it may concern:

Be it known that I, GUSTAV A. ANTEL- MANN, a citizen of the UnitedStates, residing at New Haven, in the county of New Haven and State. ofConnecticut, have invented certain new and useful Improvements in Looksfor Automobile-Doors; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

The invention relates to improvements 1n locks for automobile doors andthe like The object of the present inventlon is to improve theconstruction of locks for automobile doors and various other closuresand to provide a simple, practical and comparatively inexpensiveautomobile lock adapted to be operated by either a knob or handle or alever at the upper edgeof the door and capable when the latter is closedof automatically engaging a fixed catch or keeper whereby the door willbesecurely locked.

With these and other invention consists in the construction and novelcombination and arrangement of parts hereinafter fully described,illustrated in the accompanying drawings and pointed out in the claimshereto appended, it being'understood that various changes in the form,proportion and minor details of construction may be resorted towithout-departlng from the spirit or sacrificing any of the advantagesof the invention.

In the drawing Figure 1 is a plan v1ew of a portion of an automobiledoor and body provided with a lock constructed 1n accordance with thisinvention, Fig.2 is a side elevation of the lock, the face plate beingremoved, Fig. 3 is a detail view of' the fixed catch or keeper, Fig. 4is a detail v1ew of the removable faceplate of the lock, Fag. 5 1s adetail view of the spring actuated slide.

Like numerals of reference designate corresponding parts in the severalfigures of the drawing. I I

In the accompanying drawing in which'is illustrated the preferredembodiment of the invention, the automobile door lock comprises in itsconstruction, a pair of upper and lower horizontally disposed locklnglevers 1 pivotally mounted at their rear ends in asuitable lock casing 2and extending outwardly beyond the same and adapted to engage a taperedlug or pro ectmg portlon 3 Specification of Letters lfatent.

of a fixed catch or keeper. The lock casing which is provided with aremovable face plate. 4 is mounted on the door 5 and-the fixed catch orkeeper is'provided with an attaching plate'6 which is secured by screws7 or other suitable. fastening devices body 8 of The locking levels 1are. shownin a horizontal position in which they operate when the lockis applied to the door 'of an. automobile but of course it will bereadily un .derstood that the lock may be used for various other.purposes and the levers will operate vertically as well as horizontallyor to the the automobile as clearly illus-" trated 1n Fig. 1 of thedrawing. 5

in fact in an position; The locking levers are provide at their rearends with inwardly curved portions 9 which are overpivot 10 andthe saidlocking levers are urged inwardly toward each other and maintainednormally in their engaging position by upper and lower flat springs 11coiled at one end at 12 to increase their resiliency by providing springbends and having their other ends free and bearing against the outerside edges of the locking levers.

The locking levers are provi inner side edges at points intermediate oftheir ends with tapered notches 13 forming ded at their upper and lowerinclined faces and receiv;

ing a tapered or wedge shaped portion 14 of a spring actuated slide 15which is adapt- "ed to be actuated by an operating lever 16 to cause thetapered or wedge. shapedportion 14 of the slide to engage the inclinedfaces or edges of the notches 13 and spread or open the locking leversto release the fixed catch or keeper and enable the door'to open. Theslide 15 is provided with an opening 17 in which operates a coiledspring 18.which urges the slide forwardly or outwardly. -The inner orrear end of the slide is provided with a slot or recess 19extendinglOngitudinally of the slideand engaging a pin or stud 20 forsupporting the'iinner or rear end of the slide.

The operating lever 16 which is arranged in an upright position 1sprovided at its upper or outer end with a suitable head or handle 21 andit has an opening 22 inits lower end to receive a suitable pivot 23.

The operating lever extends through the locking'levers and through. theslide and is adapted to engage a rounded face 24 thereof whereby it isadapted to be readily operatedurging the wedge around the same.

to actuate the slide against the action of the coiled spring 18. Thelocking levers are also adapted to be spread by opposite lugs 25 of ahub 26 which is mounted on a spindle 27 adapted to carry a suitable knobor handle 28 whereby the spindle is partially rotated to operate the huband carry the lugs into engagement with the inner edges of the lockinglevers. The locking levers are provided at the hub with recesses 29which presents curv'ed faces to the hub and enables the locking leversto fit closely What is claimed is 1. A lock of the class describedincluding a pair of-lockin inner or rear en s, a slide located betweenthe locking levers, said slide and locking levers having coacting meansfor spreading the levers when the slide is moved in one direction andmeans for urging the levers v inwardly.

2. A lock of the class described including a pair of pivoted lockingsubstantial parallelism, a Wedge operating between the levers andadapted to spread the same, a spring for in one direction and a leverfor moving the wedge in the opposite direction.

3. A lock of the class described including a pair of pivoted leversarranged in sublevers pivoted at their levers arranged in reclprocatorystantial parallelism and in spaced relation, said levers being providedat their inner edges with inclined faces, springs for urging the leversinwardly, a slide operating between the levers and slidably supported atone end and provided with a tapered or wedge shaped portion operating inthe said recessesv and an operating lever extending through the slideand the locking levers and adapted to actuate the slide to spread thesaidlocking levers.

4. In a lock of the class described including a pair of pivoted leversarranged in substantial parallelism, and in spaced relation, said leversbeing I edges at points intermediate of their ends withinclined faces,springs for urging the levers inwardly, a slide operating between thelevers and slidably supported at one end and provided with a tapered orwedge shaped portion operating in said recesses, said slide providedwith an opening, and a spring mounted in said opening adapted to urgethe slide forwardly to permit the closing of the locking levers.

In testimony whereof I ailix my signature in presence of two witnesses.
